Also, debugger do not trigger, neither in pharo2 nor pharo3, for example 
putting this on rootcomponent>>#renderContentOn: html
html text 'test'.

Makes an error to raise in browser, but do not trigger debugger inside 
Pharo, which makes debugging really hard, as the browser error do not give 
enough information alone to locate the error.
